TMI my tummy is showing! Advice needed!! 😊

I have struggled and I mean STRUGGLEDe  with my weight my whole entire life and I have always kinda fluxuated between being healthy or bigger or smaller. But this right here is the absolute smallest I have ever been in my almost 20 years of life. I am 5ft 4inches and 154 pounds as of this morning. In August of 2016 I weighed in at 199 lbs!! I have a question for any ladies who have lost weight and have excess skin, are there any creams or oils you've found helpful in tightening your skin? My skin is not exactly saggy in my stomach but unfortunately I feel as if my breasts are ruined.. any advice would be so appreciated. Self love and body positivity to all you ladies!!!❤️💋
